Use this as a public-safe strategy lens. The original report is A-share focused, but the framework is useful across A-shares, U.S. stocks, Japanese stocks, and other equity markets when adapted to each market's own liquidity, investor structure, policy regime, and sector composition.

Do not wait for the user to explicitly say `主线`, `资金`, `博弈`, or `周期`. During problem decomposition, actively ask whether the user's market, sector, stock, or theme question has a hidden regime dimension. If it can change the conclusion, expand the analysis with the relevant parts of this reference.

## Reading And Application

This reference is intentionally richer than a short checklist. When applying it:

- first scan the headings and choose the relevant sections for the current task;
- read the selected sections and nearby guardrails carefully enough to apply them correctly;
- read the whole file when the task is broad, strategic, or ambiguous;
- do not rely only on stale memory or a heading-only scan.

## Core Idea: Cognitive Repricing

The key strategic idea is that equity markets do not simply trade the current economy. They trade changing recognition of the future economy. A bull or bear transition often begins when the market abandons an old growth narrative and reprices a new one.

For global use, translate this as `narrative recognition x evidence x capital acceptance`:

- `Narrative recognition`: investors begin to agree that a new industry, macro regime, business model, or policy direction matters.
- `Evidence`: adoption, orders, margins, earnings revisions, policy execution, capex, or cash-flow data support the narrative.
- `Capital acceptance`: leaders rise, pullbacks are bought, peers broaden, and funds keep returning after corrections.

If recognition rises but evidence or capital acceptance does not, treat the story as concept heat. If evidence is strong but capital refuses to price it, look for liquidity, positioning, valuation, or timing constraints.

## Four-Lens Market Map

Judge an equity market through four linked lenses:

1. `Mainline`: the durable industry or macro narrative that can absorb capital over multiple quarters or years.
2. `Funds`: the liquidity and positioning cycle that decides whether capital can keep pushing the narrative.
3. `Game`: the investor-structure and policy/institutional feedback loop that shapes volatility, squeezes, rotations, and reversals.
4. `Cycle`: the current phase of the first three forces on the time axis.

Do not explain a market only from one dimension. A strong industry story can fail when liquidity tightens; abundant liquidity can produce only short rebounds if no durable mainline exists; a good macro backdrop can still trade poorly if positioning is crowded and price rejects the story.

## Mainline

Mainline is the direction in which the market believes the economy, industry structure, or profit pool is being reorganized. It is not simply a hot sector, a one-day policy headline, or a stock with the largest short-term gain.

Analyze mainline on three layers:

- `Micro`: technology, product, cost curve, business model, penetration, orders, and company-level earnings path.
- `Meso`: industry chain migration, concentration, localization, supply-demand balance, capex cycle, and sector profit distribution.
- `Macro`: national strategy, demographic or productivity shift, energy transition, inflation/deflation regime, global supply-chain reallocation, or monetary/fiscal regime.

A candidate mainline is stronger when it has:

- a large addressable demand or structural transition;
- policy, technology, or business-model validation;
- adoption, penetration, order, capex, revenue, margin, or earnings evidence;
- leader strength plus broadening peer confirmation;
- capital returning after corrections, not only one-day attention;
- an expectation reset that creates room for further positive revisions.

Separate two mainline shapes:

- `Incremental mainline`: a new product, technology, or demand curve moves from early adoption into acceleration. It can produce stronger beta and larger valuation expansion, but it also burns out faster when expectations overshoot.
- `Stock-reallocation mainline`: an old industry rerates because concentration improves, supply is disciplined, shareholder return rises, or cash-flow quality becomes scarce. It is usually less explosive but can last longer.

## Penetration And Adoption

For technology or industry themes, adoption/penetration helps locate the mainline lifecycle:

- `0%-5%`: recognition stage. The theme can be powerful but evidence is incomplete; volatility and false starts are common.
- `5%-35%`: acceleration stage. Adoption, earnings expectations, valuation, and capital inflow can reinforce each other.
- `35%-80%`: maturation stage. Revenue can still grow, but valuation expansion usually becomes harder and stock selection matters more.
- `80%+`: saturation stage. The market needs concentration, cash return, overseas expansion, or productivity gains; pure penetration logic is mostly exhausted.

Do not fabricate penetration data. If reliable adoption data is unavailable, proxy the lifecycle with breadth, leader/follower quality, revisions, order/capex evidence, and whether good news still moves price.

## Mainline Feedback Loops

Mainlines reinforce themselves when the sequence works:

```text
adoption or structural evidence -> earnings/revision upside -> valuation expansion -> capital inflow -> industrial capital expansion -> more evidence
```

They also end through a reverse sequence:

```text
valuation overdraw -> capital leaves -> expectations fall -> capex or orders slow -> evidence weakens -> valuation contracts
```

The practical rule: never judge the mainline only by the story. Check whether evidence, price acceptance, and capital flow are still reinforcing each other.

## Mainline Termination

Use three termination types:

1. `Natural maturity`: adoption or profit growth slows; valuation stops expanding; good news generates weaker price response.
2. `Logic invalidation`: policy, technology route, business model, demand, or earnings evidence breaks the thesis.
3. `Liquidity suffocation`: the thesis remains plausible, but incremental money leaves because of rates, de-risking, leverage reduction, issuance, crowded positioning, or a competing mainline.

These have different strategy implications. Natural maturity calls for lower return expectations and more selective holdings. Logic invalidation calls for thesis reset. Liquidity suffocation calls for patience: do not upgrade again until leaders stabilize, breadth repairs, and capital returns.

## Funds

Funds decide whether the market has both willingness and ability to price the mainline. Separate three layers:

- `Macro liquidity`: rates, credit, central-bank direction, fiscal impulse, FX, inflation, and broad risk premium.
- `Market liquidity`: equity fund flows, ETF flows, margin/leveraged money, buybacks, issuance, short interest, option positioning, and trading volume.
- `Structural liquidity`: where incremental money concentrates by sector, factor, market cap, region, and theme.

Watch transmission lags. Macro easing may first appear in credit or interbank conditions before reaching equities. A policy or rate turning point is not the same as equity-market liquidity confirmation.

For global markets:

- U.S.: rates, real yields, dollar, credit spreads, buybacks, ETF flows, mega-cap index weight, options/gamma, and earnings-revision breadth.
- Japan: USD/JPY, JGB yields, foreign investor flow, shareholder-return reforms, exporters, banks, domestic reflation, and global semiconductor cycle.
- A-shares: policy impulse, credit, fund issuance, margin balance, northbound/foreign flow where relevant, turnover, limit-up structure, and theme concentration.

## Game

Game is the mechanism that turns the same story and liquidity into different price paths. It includes investor structure, rules, positioning, and feedback loops.

Ask:

- Who is the marginal buyer: retail, long-only institutions, hedge funds, quant, ETF, passive index, corporate buyback, foreign capital, or short covering?
- What mechanism is amplifying the move: limit-up/down, options gamma, ETF rebalancing, forced de-risking, policy communication, short squeeze, margin pressure, or benchmark chasing?
- Is the market rewarding confirmation, chasing symbols, squeezing shorts, or rotating defensively?
- Are leaders pulling followers up, or are followers failing while leaders mask distribution?

In A-shares, game structure often shows up through theme boards, limit-up quality, 股吧 heat, turnover, regulatory/policy expectations, and retail/institutional mismatch. In U.S. markets, options/gamma, passive flows, short interest, mega-cap concentration, and earnings-revision acceptance are often more important. In Japan, foreign flow, FX sensitivity, governance reform, and global-cycle positioning often dominate.

## Cycle

Cycle is the time coordinate of mainline, funds, and game. Use it to decide posture, not just explanation.

Practical four-phase map:

1. `Emergence / 起势`: skepticism remains, leaders resist weakness, liquidity begins to improve, and the market starts researching a new direction. Focus on research, selective entry, and early leader identification.
2. `Expansion / 乘势`: leaders trend, followers broaden, money-making effect improves, revisions and liquidity reinforce each other. Focus on holding leaders, buying healthy pullbacks, and avoiding premature exit.
3. `Divergence / 转势`: leaders still look strong, but breadth, volume-price quality, valuation, revisions, or liquidity deteriorate. Focus on risk control, leader/follower discrimination, and staged profit-taking.
4. `Retreat or Reset / 退势`: leaders break, liquidity leaves, loss effect spreads, and former mainline becomes research material. Focus on defense, cash, and building the next watchlist rather than forcing trades.

The cycle lens should change the final answer. The same stock can be a buyable leader in emergence, a hold in expansion, a do-not-chase in divergence, and only a research candidate in retreat.

## Dynamic Relationships

Use these interactions when a market looks contradictory:

- `Mainline creates funds`: a convincing trend can attract capital before broad liquidity is obvious.
- `Funds accelerate mainline`: liquidity turns a good thesis into a broad bull leg.
- `Game shapes path`: rules, crowding, derivatives, and investor structure decide whether the path is smooth, rotational, or violent.
- `Cycle changes meaning`: the same headline is accumulation fuel early, but exit liquidity late.
- `Funds without mainline`: produces rebounds, squeezes, or factor rotations, but weak durability.
- `Mainline without funds`: produces watchlist names or relative strength, but may not sustain a bull leg until liquidity returns.

## Market-Sector-Stock Resonance Interface

When a daily strategy or close review asks whether a collective sector/theme surge can continue, load the installed or sibling `stock-sentiment-analysis` skill and use its `references/sentiment-framework.md` as the detailed shared method. The compact mnemonic is:

`强大盘 + 高成交 + 上涨家数多 + 完整产业链扩散 + 基本面持续验证 + 非末端加速`

This is not a mechanical score. A late-cycle climax can negate otherwise strong market, turnover, and breadth evidence. A sector can also become a new main line before the broad market is fully strong, but it then needs exceptional relative strength, repeated capital return, and peer follow-through.

Translate the result into three separate judgments:

- `Logic durability`: structural demand, policy, adoption, orders, earnings, revisions, or cash-flow evidence.
- `Tape continuity`: broad-market support, liquidity, participation, sector-chain breadth, leaders/followers, and price acceptance.
- `Entry quality`: recognition/emergence, healthy expansion or pullback, versus terminal acceleration and crowded chase.

Finish at the correct hierarchy: `market -> sector/theme -> decisive stocks`. Do not call a sector durable because one index heavyweight rose, and do not call an individual stock attractive merely because its sector thesis is durable.

## Cross-Market Adaptation

For A-shares:

- Give more weight to policy direction, sector/theme breadth, retail emotion, limit-up/limit-down structure, fund-flow concentration, and institutional/retail two-layer behavior.
- Mainlines often appear as policy-supported industry trends and theme clusters.

For U.S. stocks:

- Give more weight to earnings revisions, free cash flow, buybacks, rates, index concentration, options/gamma, ETF flows, and mega-cap leadership.
- Mainlines often appear as productivity/technology waves, platform shifts, capex cycles, or margin/earnings revisions.

For Japanese stocks:

- Give more weight to yen, global cycle exposure, shareholder-return reform, governance change, foreign-investor flows, exporters, banks, semiconductors, and domestic reflation.
- Mainlines often combine structural reform, global demand, FX, and balance-sheet rerating.

For global risk-on/risk-off:

- Check rates, dollar, yen, volatility, credit, commodities, index breadth, and cross-market leadership.
- A theme is more durable when it survives higher-rate or risk-off tests and still attracts capital after pullbacks.

## Output Use

When writing strategy reports, do not paste this methodology mechanically. Convert it into decision-relevant conclusions:

- current mainline candidates and their evidence quality;
- whether liquidity supports them or merely permits a rebound;
- what game mechanism explains the current speed, volatility, or rotation;
- the likely cycle phase;
- what confirms continuation;
- what invalidates the view;
- whether the right action is attack, hold, rotate, reduce risk, defend, or wait.
